Customer Questions and Answers for Electronic Control Board by Whirlpool

Carol, You will want to check the heating circuit and make sure that you are purging the water line before running the dishwasher. The water temp coming into the unit can affect the operation and should be at least 120 degrees coming into the unit. If this checks ok then test the heating circuit to make sure that it is working as this can cause the unit to run for extensive periods of time trying to get the water temp to the proper temperature. If all this checks ok then the issue will be with the control board.
